A terminal attachment method and device

Abstract

The invention provides a terminal attachment method and device. The method includes: receiving a system information block SIB message broadcast by a base station eNodeB; judging the current mobility management entity MME scenario according to the system information block SIB message; if it is determined that the current mobility management entity MME scenario is a mobility management entity resource pool MME In the POOL scenario, determine whether the weight of the local mobility management entity MME is the largest according to the system information block SIB message; if it is determined that the weight of the local mobility management entity MME is not the largest, delete the local mobility management entity code MME CODE; Send an attachment request message to the base station eNodeB to perform terminal attachment. The embodiment of the present invention determines whether it is an MME POOL scenario and determines whether the weight of the local MME is the largest in the MME POOL scenario. If not, the local MME CODE is deleted, and the initial terminal selects the MME according to the weight and attaches, reducing The probability of device overload can better achieve load balancing of MME POOL.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, and in particular, to a method and device for attaching a terminal. Background technique [0002] Mobility Management Entity Pool (Mobility Management Entity Pool, MME POOL), MME POOL refers to an area composed of at least one MME, which is a collection of complete Tracking Area (TA), and a terminal (UserEquipment, UE) in the MME POOL The TA area move may not replace the service MME. [0003] In order to achieve load balancing of network resources, a weight is set for each MME in the MME POOL, so that the base station eNodeB selects the serving MME according to the size of the weight factor. The selection of the serving MME is based on the network topology. Generally, the principle of selecting the serving MME is to reduce the probability of future MME handover as much as possible. Therefore, in order to avoid unnecessary signaling overhead in the core network, a UE already...
